High Quality Content by WIKIPEDIA articles! Yellow Thunder (Ho-chunk name Wahkanjahzeegah also given as Wakunchakookah, born in 1774) was a chief of the Ho-Chunk tribe. Historians state that he and his fellow chiefs were persuaded to sign their lands over to whites without realizing what they were doing. After signing over their lands, in what is now the area of Green Bay, Wisconsin, the tribe was given eight months to leave. Yellow Thunder and other chiefs traveled to Washington D.C. in 1837 to assert their claims, but President Andrew Jackson would not meet with them. Yellow Thunder and his people refused to move, and in 1840, United States Army troops arrived to force them to do so. Yellow Thunder was briefly chained but released, as he and his fellow chiefs realized that further resistance would lead to violence against their people and agreed to cooperate. Yellow Thunder would eventually move off the Iowa reservation and onto a 40-acre (160,000 m2) farm in Wisconsin, where he died in 1874.
